Documentation and Code for adv_tcpretrans_count doesn't align

**Describe the bug**
Based on the documentation available most of not all MetricNames can be used in the MetricsConfiguration CRD. There is at least one metric that doesn't align with this and that is 'adv_tcpretrans_count' where 'tcp_retransmission_count' instead should be used.

**To Reproduce**
Steps to reproduce the behavior:

1. Go to 'https://retina.sh/docs/Concepts/CRDs/MetricsConfiguration'
2. Go to 'https://retina.sh/docs/Metrics/modes/advanced'
3. See the correlation between the metric names
4. Use the 'tcpretrans_count' and see that the crd gets state 'Errorred'

**Expected behavior**
It should be clear documentation on what metric name should be used
